openjpeg/src/lib/openjp2/openjpeg.h, branch v2.3.0 Fork of openjpeg library for JPEG2000 encoding and decoding https://git.carlh.net/cgit/openjpeg/atom?h=v2.3.0 2017-09-19T15:48:07Z opj_set_decoded_components(): add a provision for a apply_color_transforms parameter in case we support it in the future 2017-09-19T15:48:07Z Even Rouault even.rouault@spatialys.com 2017-09-19T15:48:07Z urn:sha1:e17bbde9066600528ab523adee69d9c9c33ba157 Add capability to decode only a subset of all components of an image. 2017-09-19T15:06:19Z Even Rouault even.rouault@spatialys.com 2017-09-19T14:52:07Z urn:sha1:7e2b6bebff12eab8bdc17fc9af017e8c11652f4f This adds a opj_set_decoded_components(opj_codec_t *p_codec, OPJ_UINT32 numcomps, const OPJ_UINT32* comps_indices) function, and equivalent "opj_decompress -c compno[,compno]*" option. When specified, neither the MCT transform nor JP2 channel transformations will be applied. Tests added for various combinations of whole image vs tiled-based decoding, full or reduced resolution, use of decode area or not.
